TONGUE-TRUCK FOR HARVESTERS.

SPECIFICATION forming part 01 Letters Patent No. 760,107, dated May 17,1904.

Application filed February 8, 1904:. Serial No. 192,641. (No model.)

To all whom, it may concern:

Be it known that I, SAMUEL K. DENNIs, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Ton gue-Trucks for Harvesters,of which the following is a complete specification.

This invention relates to that style of harvester tongue-trucks in whichthe guiding tongue is caused to produce a greater angular deflection ofthe planes of the supporting- Wheels of the truck than the tongue itselfis subjected to.

The purpose of this invention is to produce a tongue-truck in which theguiding-tongue thereof shall operate through suitable connecting meansto produce greater angular deflection of the planes of the truck-wheelsthan the angular deflection of the tongue and at the same time permit offree movement of the tongue in a vertical plane without effecting themovement of the truck-wheels.

Referring to the drawings, Figure 1 is a plan view showing thetongue-truck complete and a fragment of the reel of a harvester in theirapproximate relative positions. Fig. 2 is an enlarged plan view of thetruck, only a portion of the stub and the guidingtongues being shown,however, and the relative position of the several parts when turningbeing shown in dotted lines. Fig. 3 is a transverse section of the truckas indicated by the line 3 3 of Fig. 2, with one wheel shown in section.Fig. 4 is a partial longitudinal section of the truck as indicated bythe line 4 4 of Fig. 2.

In the drawings, A designates the stubtongue of the tongue-truck, and Bthe axle, pivotally connected thereto. On either end of the axle B arethe downwardly-projecting bosses 6, provided with apertures which engagethe vertically-extending stems c of the truck-wheel bearings C. Thesetruck-wheel axle B are secured the arms a.

the free ends of these arms 0 with the stub tongue A are the links f. I

G is the tongue for guiding the truck, pivotally connected to the axleB, the pivotal connection being effected by means of the eyebolts 9,thus making the tongue rigid laterally with respect to the said axle B,but permitting it to move freely in a vertical plane.

It will be seen that as the tongue G is deflected or moved laterally theaxle B and the truck-wheel bearings mounted thereon will move with it,and the links f f will restrain the movement of the free end of the arms(2, which will cause the said bearings C to move about the spindle c ofthe wheel-bearing C, deflecting the truck-wheels D an amount dependingupon the extent of movement of the said tongue and also upon the lengthof the arms 6. In this way the truck-wheels will be subjected to agreater angular deflection than the angular deflection of the tongue G,and the lines of the-axis of the truck-wheels will thus be brought topass through or nearthe correct pivotal center about which the harvesterto which the trucks are attached is turning.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a tongue-truck for harvesters, in combination, ahorizontally-swinging axle pivotally connected to the frame of thetruck, a guiding tongue pivotally secured thereto, truck-Wheel supportshaving vertically-dis posed pivotal bearings on either end of saidswinging axle, truck-wheels journaled on said supports, and meansinterposed between the truck-wheel supports and a fixed part of thetruck-frame for controlling the position and movement of thetruck-wheels, substantially as described.

2. In a tonguetruck for harvesters, in combination, ahorizontally-swinging axle pivotally connected to the frame of thetruck, truck-wheels journaled thereon, a -guiding tongue pivotallysecured to said axle and means pivotally secured to a fixed part of theframe of said truck for controlling the movement and position of saidtruck-wheels, said means being rendered operative by the lateralmovesupport, arms rigidly secured to the verticallydisposed pivotalbearings and links connecting the free ends of said arms to a fixed partof the frame of said truck, substantially as described.
